A buildup of dark clouds is a common first indicator of an approaching thunderstorm.

Thunder and lightning, sky darkens, winds increase. A better long distance warning is crackily static on an AM radio. You can only hear thunder about 8 miles away, but the static can be heard about 40 miles away from the storm.
